That's the main thing. But there are two more numbers worth knowing.
It's 28% lighter than the competition.
Most 20,000mAh 65W banks weigh around 400-450g. The Carbo 20K weighs 320g.
The housing is carbon fibre (67% lighter than plastic) and magnesium alloy (38% lighter than aluminium).
If you're counting grams for a trek or a flight bag, that gap is significant.
It stores 22% more usable energy. The rated capacity is 67.5Wh compared to the 55Wh you get from most 20,000mAh banks.
In real terms, that's roughly 4 full charges of an iPhone 17 or one full charge of a MacBook Air with juice left over.
The math on weight-to-energy:
Carbo 20K Gen2:
67.5Wh at 320g = 0.211 Wh per gram
Typical 20K 65W bank:
55Wh at 450g = 0.122 Wh per gram
Gram for gram, it carries 73% more energy. For the same weight budget in your pack, you get significantly more power.
As promised, value in under a minute.
If you're the type who carries one bag and expects everything in it to survive whatever the day throws at you, the Carbo 20K Gen2 is $299 on our store.
